ROBERT S; DRUMMONB, F TiETROIT, MICHIGAN, ASSIGNOR T0 DETROIT STEEL PRODUGTS COMPANY, OF DETROIT, MICHIGAN, A CORPORATION OF MICHIGAN.-

METALLIC wmnow-sasni To all whom it may concern 4 Be it known that 1, ROBERT S. DRUMMOND, a citlzen of the United States of America,

' residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Metallic lVindow-Sasbes, of which, the following is a specification, reference being had therein to the accompanying drawings.

T he invention relates to metallic window sashes and has'more particular reference to certain features of construction by which adjacent sash sections may be secured to each other so as to provide for expansion and contraction, and also to form a weathering joint.

In the drawings: .Figure l is a front ole-- vationof asash formed of a plurality of sections. Fig. 2 is an enlargedhorizontal section showing the joint between sections. Fig. 3 is a similar view showing a modified construction; and Figs. 4c and o are similar views showing other modifications.

My improved sash comprises essentially a plurality of sections which are spaced from each other to provide for expansion, one of said sections bemg also prov ded with a flange which overlaps the adjacent section and forms a weathering joint. The sections are secured to each other by suitable means,

which will permit of expansion and contraction, and at the same time will hold said sections always in truealineinentf As shown in Figs. '1 and 2, A A and {A are the'several sections of the sash, the adjacent rails of Which are spaced from each other. One of the adjacent rails is formed of a Zbar B, having an outwardly-extending flange C which overlaps the rail of the adjacent sash and covers the' space therebetween so as to weather the joint The adjacent rails are mechanically secured to each other by bolts D'which pass through the parallel webs or flanges of adjacent rails and hold the sections in aline- 'ment while,permitting them to move toward or from each other in expanding and con- I tracting.

In Fig. 3, a modified form of securing means is shown, in which the adjacent rails E and .F-are held in alinement by a plate G which is secured by bolts H to the -alined flanges of said rail. These bolts through slotted bolt holes I in the plate Specification of Letters Eatent,

which provide for expansion and contrac tion. In Fig. 4 another modification is shown. in which, in place of a Z-bar, angle bars and K form the adjacent rails, while one or said bars has secured thereto anotherangle bar L,'wh ich forms in efiect a Z-bar and j ner to the construction shown in Fig.2. These sash sections may be secured'together by either or both of the securing means as shown in Figs. 2 and 3, a bolt M being' Patented Nov. 2, 1915.

overlaps the. adjacent rail in a similar'manshown as passing through the parallelly' arranged spaced flanges of the rails, While a plate N is secured by bolts 0 to alined faces of said rails.

' In Fig. 5, the sash sections are also formed of angle bars P and Q, which are spaced from each other, while a T-bar R is 9.1-

ranged with its web extending. into the space between said'bars P and Q, the head of the T overlapping the edges of said bars.

A bolt passes through the parallel flangesof the sash rails and also the web of the T and secures the parts to each othen'while permitting of expansion.

With all of the constructions as above described, the sash sections are held in true dows, sash sections provided with edgerails,

one of said sections having its edge rail spaced from an adjacent section, a flange on said first-mentioned section extendingoutward and overlapping the adjacent section, and a belt for securing said sections to each other permitting of independent movement.

An expansion joint for metallic Windows, com prising\ a plurality of sections having parallelly-aisanged spaced edge bars, a. flange on one bar overlapping the edge of the adjacent bar and weathering the joint therebetween, and a bolt connecting the parallel portions of said sections to hold the same in alinement and permitting of expansion and contraction. r I

3. In an expansion joint for metallic windows, sash sections provided with edge rails, one of said sash sections having its edge rail spaced from an adjacent edge rail of a second section, a flange on said first-mentioned section extendingbutward and overlapping spaced flanges to hold the same in alinement the adjacent edge rail, and adjustable means and permitting of expansion and contracior securing said'edge rails -to each other, tion, said bolt' securing said overlapping permitting ofindependent movement. 3; member in position upon itsvsa sh rail. 5 4.
